6 Troubleshooting

6.1Unable to Manually Set IP Addresses for the iLOs

1.Verify that the iLOs are set to DHCP enabled.

2.Power down the node.

3.Then power it on and watch the monitor as the system boots. Early in the boot process, a message appears on the screen that says "F8 to configure". Press F8.

4.Follow the configuration menu to find the DHCP setting and disable it.

6.2Changing External IP Addresses

The netinfo file is only read the first time cluster_config runs. Thus, manually changing netinfo and rerunning cluster_config does not cause the database to be updated with the new IP address, because there is already an entry in the database. To get this to work, you can update the /etc/sysconfig/network-scripts/ifcfg-ethXfile; where X is your external network adapter (probably eth1) with the 16.118.48.57 address. Then perform a service network restart. This change remains in the file until the next time you run cluster_config, which then reads in the old values from the database. To permanently change this value, either run reset_db then rerun cluster_prep and cluster_config, or manually update the IP address in the database with mysql commands.

For example:

1.Copy the file:

# cp /etc/sysconfig/network-scripts/ifcfg-eth1 /tmp/ifcfg-eth1.bk

2.Using a text editor, edit the /etc/sysconfig/network-scripts/ifcfg-eth1 file with the correct external entries. The file looks like Example 6-1, with entries that correspond to your external network information and MAC address of the eth1 device.

Example 6-1 Contents of network-scriptsFile

3.Modify the database:

#/opt/hptc/sbin/device_config --host n1 --type External --ipaddr <external IP address> --netmask <external netmask> --gateway <external gateway> --device eth1 <mac address of eth1>

Where the network information and MAC address are the same as in the file in Example 6-1.
